When trying to start the server on a brand new hello-world app creation and install of Elixir

mix phx.server

Any ideas to what I might have done wrong?

Hi @chrisolsen can you copy and paste your mix.exs file here?

Hello Chris.
I ran into something possibly similar a few days ago. I installed Elixir on a Debian system and I had to install the package “erlang-xmerl” in addition to make it work.

Just in case this is the same issue for you, I also installed two more packages until it worked: erlang-dev, erlang-dialyzer.

Hmmm, the Debian packaging makes some… interesting choices. The Elixir package depends on a handful of erlang-* packages but NOT the top-level “dummy” package for Erlang, so installing Elixir from nothing will only pull in parts of the full system.

Consider installing the whole Erlang distribution with your package manager before installing Elixir to avoid missing files like this.

Installing erlang is what did the trick!

Thanks for the help everyone :grinning:
